BACKGROUND:Abortion is one of the most important factorsreducing lambing rate and consequently profitability of sheepfarms. In addition to financial losses, it is also important from azoonotic point of view. OBJECTIVES: The aim of this study wasto investigate bacterial abortifacient agents in an outbreak ofabortion occurring in Afshari sheep in the northwest of Zanjanprovince. METHODS:Vaginal s...

the objective of the present study was to investigate the effects of a sustained-release multi-trace element ruminal bolus on sex ratio, the reproductive performance and lambs growth of afshari ewes. eighty afshari cycling ewes during breeding season were used in the trial. the animals were synchronized using cidr for 14 days and assigned into 4 groups including: group 1 (n=20) received a singl...

A new biologically-inspired vision sensor made of one hundred “eyes” is presented, which is suitable for real-time acquisition and processing of 3-D image sequences. This device, named the Panoptic camera, consists of a layered arrangement of approximately 100 classical CMOS imagers, distributed over a hemiThis research has been partly conducted with the support of the Swiss NSF under grant num...
